Scientists uncover earliest evidence of fire use to manage Tasmanian landscape
2024-11-15
Some of the first humans to arrive in Tasmania, over 41,000 years ago, used fire to shape and manage the landscape, a new study from The Australian National University (ANU) and the University of Cambridge has found.
It is thought to be the earliest and most detailed record of humans using fire in the Tasmanian environment.
According to the researchers, early inhabitants of Tasmania were managing forests and grasslands by burning them to create open spaces, possibly for food procurement and cultural activities.
The team analysed traces of charcoal and pollen contained in ancient mud that showed how Indigenous Tasmanians (Palawa) ...
Interpreting population mean treatment effects in the Kansas City Cardiomyopathy Questionnaire
2024-11-15
About The Study: Inferences about clinical impacts based on population-level mean treatment effects may be misleading, since even small between-group differences may reflect clinically important treatment benefits for individual patients. Results of this study suggest that clinical trials should explicitly describe the distributions of Kansas City Cardiomyopathy Questionnaire change at the patient level within treatment groups to support the clinical interpretation of their results.

Stress makes mice’s memories less specific
2024-11-15
Stress is a double-edged sword when it comes to memory: stressful or otherwise emotional events are usually more memorable, but stress can also make it harder for us to retrieve memories. In PTSD and generalized anxiety disorder, overgeneralizing aversive memories results in an inability to discriminate between dangerous and safe stimuli. However, until now, it wasn’t clear whether stress played a role in memory generalization.
Now, neuroscientists report November 15 in the Cell Press journal Cell that acute stress prevents mice from forming specific memories. Instead, the stressed mice formed generalized memories, which are ...
Research finds no significant negative impact of repealing a Depression-era law allowing companies to pay workers with disabilities below minimum wage
2024-11-15
PHILADELPHIA—Debate continues to swirl nationally on the fate of a practice born of an 86-year-old federal statute allowing companies to pay workers with disabilities subminimum wages: anything below the federal minimum wage of $7.25 an hour, but for some roles as little as 25-cents-per-hour. Those in favor of repealing this statute highlight assumptions about reduced productivity along with the unfairness of this wage level—often used elsewhere to pay, for example, food service workers who typically make additional wages in tips. Those against repeal have voiced concerns that, without subminimum ...
Resilience index needed to keep us within planet’s ‘safe operating space’
2024-11-15
EMBARGOED: NOT FOR RELEASE UNTIL FRIDAY 15 NOVEMBER 2024 AT 11:00 ET (15:00 UK TIME).
Researchers are calling for a ‘resilience index’ to be used as an indicator of policy success instead of the current focus on GDP.
They say that GDP ignores the wider implications of development and provides no information on our ability to live within our planet’s ‘safe operating space’.
In a paper published today [15 November] in the journal One Earth, researchers from the University of Southampton, UCL ...
How stress is fundamentally changing our memories
2024-11-15
Researchers at The Hospital for Sick Children (SickKids) have uncovered that stress changes how our brain encodes and retrieves aversive memories, and discovered a promising new way to restore appropriate memory specificity in people with post-traumatic stress disorder (PTSD).
If you stumble during a presentation, you might feel stressed the next time you have to present because your brain associates your next presentation with that one poor and aversive experience. This type of stress is tied to one memory. But stress from traumatic events ...

In vitro model enables study of age-specific responses to COVID mRNA vaccines
2024-11-15
mRNA vaccines saved lives during the COVID-19 pandemic, but older people had less of an immune response to the vaccines than did younger adults. Why? Boston Children’s researchers, led by Byron Brook, PhD, and Ofer Levy, MD, PhD, have found some answers, while providing proof-of-concept of a new system that can model vaccine responses in a dish.
The test system, described in a paper out today in iScience, is called MEMPHIS (Modular Evaluation of immunogenicity using Multi-Platform Human In vitro Systems). It analyzes whole human blood from people of different age groups and applies both proteomics and targeted assays to measure ...
Sitting too long can harm heart health, even for active people
2024-11-15
More time spent sitting, reclining or lying down during the day may increase the risk of cardiovascular disease (CVD) and death, according to a study in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s Scientific Sessions 2024. More than roughly 10-and-a-half hours of sedentary behavior per day was significantly linked with future heart failure (HF) and cardiovascular (CV) death, even among people meeting recommended levels of exercise.
“Our findings support cutting back on sedentary time to reduce cardiovascular risk, with 10.6 hours a day marking a potentially key threshold ...

Hunted nearly to extinction during 20th century whaling, the Antarctic blue whale, the world’s largest animal, went from a population size of roughly 200,000 to little more than 300. The most recent estimate in 2004 put Antarctic blue whales at less than 1% of their pre-whaling levels.
But is this population recovering? Is there just one population of Antarctic blue whales, or multiple? Do these questions matter for conservation?
A team led by Zoe Rand, a University of Washington doctoral student, tackles these questions ...

Zinc deficiency promotes Acinetobacter lung infection: study
2024-11-15
Dietary zinc deficiency promotes lung infection by Acinetobacter baumannii bacteria — a leading cause of ventilator-associated pneumonia, according to a new study published Nov. 15 in the journal Nature Microbiology.
A Vanderbilt University Medical Center-led team of researchers discovered an unexpected link between the pro-inflammatory cytokine interleukin-13 (IL-13) and A. baumannii lung infection, and they demonstrated that blocking IL-13 prevented infection-associated death in an animal model.
The findings suggest that anti-IL-13 antibodies, which are FDA-approved for use in humans, may protect against bacterial pneumonia in patients with zinc deficiency.

How optogenetics can put the brakes on epilepsy seizures
2024-11-15
In what could one day become a new treatment for epilepsy, researchers at UC San Francisco, UC Santa Cruz and UC Berkeley have used pulses of light to prevent seizure-like activity in neurons.
The researchers used brain tissue that had been removed from epilepsy patients as part of their treatment.
Eventually, they hope the technique will replace surgery to remove the brain tissue where seizures originate, providing a less invasive option for patients whose symptoms cannot be controlled with medication.
The ...
